* [[Franklin D. Roosevelt Lake|Lake Roosevelt]]
* [[Grand Coulee Dam#Pump-generating plant|Grand Coulee Pumping-Generating Plant]] (1953) consist of twelve pump units with combined power of {{convert|593|kW|hp|abbr=unit}}, of which six are reversible pump-generator turbine units with a combined generating capacity of {{convert|314|MW|hp|abbr=unit}}.<ref name="Columbia Basin Project Plan">{{cite web |title=Columbia Basin Project Plan |url=https://www.usbr.gov/projects/index.php?id=438 |website=Bureau of Reclamation |publisher=United States Federal Government |access-date=15 October 2024 |ref=HHH}}</ref> The pumps are used to move water from Lake Roosevelt into Banks Lake, from which it can be either sent south into the Columbia Basin Irrigation system or returned to Lake Roosevelt by the reversible generating pump-turbines to create additional electricity for the grid.<ref name=DEIS/>

===Feeder Canal, North and Dry Falls Dams, Banks Lake===
*[[Banks Lake]] (1951) is an artificial impoundment in the Upper [[Grand Coulee]]. It is {{convert|27|mi|km}} long and {{convert|1|to|3|mi|km}} wide. The coulee has nearly vertical rock walls up to {{convert|600|ft|m}} high. [[File:North Dam (4307003306).jpg|thumb|North Dam on Banks Lake with Feeder Canal]]
**[[North Dam]], near the town of [[Grand Coulee, Washington|Grand Coulee]], has a maximum height of {{convert|145|ft|m}} and a crest length of {{convert|1,400|ft|m}}. 
**[[Dry Falls Dam|Dry Falls]], or South Dam, near Coulee City, has a maximum height of {{convert|123|ft|m}} and a crest length of {{convert|8,880|ft|m}}. The crest elevation of both dams is {{convert|1580|ft|m}}. Project water enters Banks Lake through the Feeder Canal from the Pump-generating plant.<ref name=DEIS/> The outlet for Banks Lake is the Main Canal near [[Coulee City, Washington|Coulee City]]. It is near the east abutment of Dry Falls Dam.<ref name=DEIS/> Banks Lake serves as an equalizing reservoir for storage of water for irrigation and can be used to for power generation.
*Feeder Canal (1951) links North Dam at northern end of Banks Lake with the siphon outlets for the Grand Coulee Pumping—Generating plants discharge lines. It is {{convert|1.6|mi|km}} long running in an open concrete-lined canal, and a twin-barrel concrete cut—and-cover conduit.<ref name=DEIS/>
*Main Canal (1951) is {{convert|8.3|mi|km}}, including {{convert|2.4|mi|km}} of lake sections.<ref name=DEIS/>
*Bacon Tunnel and Siphon (1950) is a {{convert|1037.5|ft|m}} long sealed Siphon under the eastern extension of the Dry Falls draw.<ref name=DEIS/>[[File:Pinto Dam.png|thumb|Aerial view of Pinto Dam, Washington, USA.]]
*[[Billy Clapp Lake]] ([[Pinto Dam]] – zoned earth & rockfill) (1951) aka (Long Lake Dam) is at the south end of Long Lake Coulee. The reservoir is {{convert|6|mi|km}} long and {{convert|0.5|mi|km}} wide.<ref name=DEIS/>
